Microsoft has created a new FTP service that has been completely rewritten for Windows Server® 2008. This new FTP service incorporates many new features that enable Web authors to publish content more easily than before, and offers Web administrators more security and deployment options.

The new FTP 7.5 service supports extensibility that lets you extend the built-in functionality that is included with the FTP service. More specifically, FTP 7.5 supports the creation of your own authentication providers. You can also create providers for custom FTP logging and for determining the home directory information for your FTP users.

IMPORTANT: The latest version of the FTP 7.5 service must be installed in order to use the provider in this walkthrough. A version FTP 7.5 was released on August 3, 2009 that addressed an issue where the local and remote IP addresses in the IFtpLogProvider.Log() method were incorrect. Because of this, using an earlier version of the FTP service will prevent this provider from working.

If you have this problem on your file server, try shifting to FileZilla. If you’re looking for a good file server that you can use on your own place, FileZilla Server is a good one to try. FileZilla Server is a server that supports FTP over SSL/TLS and FTP which offers secure encrypted connection to the server.

It supports SSL which is the same encryption level supported by web browsers in protecting data. “SSL” stands for “Secure Sockets Layer.” It is the standard security technology for creating encrypted link between a web browser and a web server. With SSL, data is encrypted to make sure any meddling eyes will not be able to see it and confidential information is protected.

FileZilla Server supports on-the-fly data compression which can improve transfer rates. Sadly, the compression setting can have varying results so it is recommended to use it with care. FileZilla Server doesn’t support SSH File Transfer Protocol or SFTP. Go to FileZilla Server for Windows to download the latest. It supports Windows Vista, Windows 7, Windows 8, Windows 8.1, and Windows 10 both 32-bit and 64-bit.

Unfortunately, unlike FileZilla Client that supports other operating systems like OS X and Linux, FileZilla Server is designed for Microsoft Windows only.
